You’re a/c technician is a friend you shall see only twice in a year.
These are some of the most common issues that a skilled AC service technician can prevent with a thorough inspection and AC preventative maintenance. Two service calls a year can save you from those dreaded breakdowns on the hottest days of the season.
1. Electrical issues
Your technician will inspect all wiring and electrical connections and find and fix loose connections and worn wires before they cause a power loss that takes out your air conditioners PCB.
2. Dirty coils and Low Refrigerant Charge
Your air conditioner has evaporator coils that remove the heat from the air in your space, and condenser coils that release the heat outside the building. When the coil gets coated with dirt and grime, it can’t effectively transfer heat. That makes your system work harder and run longer to cool the space. The increased load on the fan motor and compressor can cause them to fail.
Cleaning the coils as part of AC preventative maintenance before the start of the season, and sometimes more often depending on the air quality where your air conditioner is located, takes care of this issue and prevents system failure.
Refrigerant is the substance running through your AC’s coils that removes the heat and humidity from the air. Sometimes small holes or cracks in the refrigerant lines can develop, causing the system to leak refrigerant. When that happens, your system gradually loses cooling power until it can’t cool your space at all. As part of your AC preventative maintenance, your service technician will test the refrigerant charge. If he finds a reduced level of refrigerant, he can find and fix the leak before you even realize you have a problem.
3. Faulty or improperly set controls and worn-out parts
Those new electronic controls are handy and save money on your energy bills, but they can be tricky to program. If it’s programmed incorrectly, you might end up with an air conditioner that won’t turn on (or won’t turn off!). Your service technician will test thermostats and other controls to ensure that the correct temperatures are maintained, timer functions are set properly, and batteries are changed.
When a worn belt or pulley suddenly snaps, you’ll find yourself without cooling in a hurry. But your service technician can see that the belt is worn and replace it before it causes your system to shut down.
4. Air flow problems
Delhi’s air can be rough on-air conditioning equipment, especially the fan in your outdoor unit that is continuously exposed to smog and pollution. When the blades get coated with grime, the fan speed can slow down, putting a strain on the motor and eventually causing it to fail. Cleaning the blades during AC preventative maintenance easily prevents this problem.
Faulty fan motors, blocked ducts, clogged filters and other air flow issues can cause your system to cool ineffectively and can lead to frozen coils and even a burned-out compressor. When that happens, you might need to start shopping for a new air conditioner. Finding and fixing air flow issues can prevent a much more expensive problem.
5. Clogged drain lines and drain pan
Accumulating debris in drains and condensate lines can cause them to clog and overflow. When that happens, not only will your system go down, but you’ll have water damage to deal with. If it’s a slow water leak that’s been going on for some time before you notice it, you could end up with dangerous mold growth. Clearing the lines and drains is a simple process that prevents a big mess.
